Public Types
typedef T	first_argument_type

	The type of the function object's second argument.
typedef T	result_type
	The type of the function object's result;.

Detailed Description

template<typename T>
struct thrust::plus< T >

plus is a function object. Specifically, it is an Adaptable Binary Function. If f is an object of class plus<T>, and x and y are objects of class T, then f(x,y) returns x+y.

Template Parameters

T	is a model of Assignable, and if x and y are objects of type T, then x+y must be defined and must have a return type that is convertible to T.

The following code snippet demonstrates how to use plus to sum two device_vectors of floats.

#include <thrust/device_vector.h>
#include <thrust/functional.h>
#include <thrust/sequence.h>
#include <thrust/fill.h>
#include <thrust/transform.h>
...
const int N = 1000;
thrust::device_vector<float> V1(N);
thrust::device_vector<float> V2(N);
thrust::device_vector<float> V3(N);

thrust::sequence(V1.begin(), V1.end(), 1);
thrust::fill(V2.begin(), V2.end(), 75);

thrust::transform(V1.begin(), V1.end(), V2.begin(), V3.begin(),
                  thrust::plus<float>());
// V3 is now {76, 77, 78, ..., 1075}
